I'm producing a series of flash cards in LaTeX (well, actually XeLaTeX). Each card has a title, a short paragraph of text, and a table, which is the main purpose of the card. Occasionally the paragraph references a footnote (which is laid out in the normal way at the foot of the card). The tables all occupy the same vertical height, but the paragraph above and the footnotes below (if present) can take up varying amounts of space.
I want to lay out the cards so the table appears in the same vertical position on each card, regardless of how much text there is above or below. Because of the way I'm generating the cards, I have very limited control over the LaTeX source, but unlimited control over the .sty file. In particular, I cannot wrap the table in a \textblock (e.g. as per this question). What I really want is a way of doing \vspace to 4cm, i.e. with an absolute page offset. Is anything like this possible?

\textblock". Okay, what else can you not do? Can you wrap thetabularinside something else? What about wrapping the paragraph in something? It would be ideal if you could identify all restrictions/limitations as well as some sample (compilable) code to work with. – Werner Dec 04 '18 at 23:41\end{something}or even a single close brace. I have (almost) complete control over the formatting of the title and paragraph, and can wrap these in something if that helps. If there's an environment that turns the paragraph into a fixed-height box, I can easily use that, so long as it doesn't alter the paragraph indentation. – richard Dec 04 '18 at 23:48
